5 Claims.

This invention relates to improvements in welding apparatus and, moreespecially, such appara-' the sheets. In making tanks in this way,difficulty has been encountered in alining and holding the sheets toproperly place and locate them preparatory to the welding of the edges.By the use of my improved apparatus, the sheets of steel may be properlyalined and held with their edges in proper position for welding.

My improved apparatus is cheap to manufacture, strong and rugged, andgreatly facilitates the welding of various members, especially the edgesof steel sheets as mentioned above.

Other features and advantages 01 my invention will appear more fully asI proceed with my specification.

In that form of device embodying the features of my invention shown inthe accompanying drawings- Figure 1 is a view in side elevation of aportion of a steel structure, for example, a tank, showing some bottomand side plates in position for the butt-welding of their edges; Fig. 2is a view taken as indicated by the line 2 of Fig. 1; Fig. 3 is a viewtaken as indicated by the line 2 of Fig. 1; Fig. 4 is an enlargedvertical sectional view showing the welding of a side sheet onto abottom sheet; Fig. 5 is a view taken as indicated by the line 5 of Fig.1; Fig. 6 is an enlarged view in front elevation of my improved weldingapparatus; Fig. '7 is a sectional view showing the welding oi twoadjacent edges of the side sheets of a tank or similar structure; Fig. 8is a view similar to Fig. 1, showing a modified form; Fig. 9 is a viewtaken as indicated by the line 8 of Fig. 8; Fig. 10 is a view taken asindicated by the line III of Fig. 8; and

. Fig. 11 is a view similar to Fig. 10, showing a modiflcation.

As shown in the drawings, III, II and I2 may indicate sheets or platesof steel iorming the side wall, for example, of a cylindrical tank and I3, one of the bottom sheets. The side sheets are butt-welded togetherand the bottom of the lower side sheet I2 meets the bottom sheet I3 atright angles, as shown in Fig. 4, so that the bottom sheet has aprojecting margin I3 outside 01' the side sheet I2. I4, I4 indicate thewelding of the sheets. In Fig. 7, I 5 indicates the welding of the edgesof the sheets II and I2.

I shall first describe the apparatus used for (CI. u'a-sal holding theside sheets II and I2 or I and II. This includes a rectangular plate I6with two square holes I1 and I8 adapted to receive apertured holdinglugs I9 and 20 on the sheets I I and I2. 2| and 22 indicate wedgesadapted to be driven through the apertures in the holding lugs I8 and2|! to draw the sheets II and I2 against the plate I8 to bring-thesesheets into the same plane.

The plate I5 is provided with bars 23 and 24 above and below the upperhole I1 and similar bars 25 and 28 above and below the lower hole IS.The sides of these bars form shoulders adjacent the apertures I1 and I8.21 indicates a wedge adapted to be driven between the bar 23 and theholding lug 29 in order to shift the sheet II laterally with respect tothe plate I6. I am using the term laterally to indicate the shifting ofa sheet in any direction in the same plane. That is, the side sheets byproper positioning of the apparatus may be shifted upwardly, downwardlyor sidewise; and, likewise, the bottom sheet may be shifted in anydirection in its own plane. A wedge driven between'the bar 24' and theholding lug is will serve to shift the'sheet upwardly. 5 In like manner,the sheet I2 may shift either downwardly or upwardly by means of a wedgebetween the holding ing and the bar or 26. The wedge 28 is shown in thelatter position to shift the sheet I2 upwardly. 30

The improved welding apparatus is also shown between sheets I0 and IIand it will be seen that in this position the wedges 29 and 3|! can beused to shift the sheets in and I I sidewise with respect to the plateI6. The holding lugs I9 and 20 may be attached to the sheets II and I2in any suitable manner as by welding and may be removed after the edgesof the-sheets have been permanently welded together. 4 In Figs. 2 and 3,I have shown the invention adapted for holding aside sheet I2 in properposition to have its lower edge welded to theupper surface 01' a bottomsheet I2. As here shown, the holding plate I6 instead of being flat isangular. I have indicated this plate by the numeral IIB. Its upperflange has the hole II! and its lower flange, the hole 8, these holesadapted to receive the holding lugs I I9 and I20 attached to the sidesheet I2 and bottom sheet I3, respectively. 5 The wedges I2I and I22 areutilized to draw the sheets tightly against the plate 6. Above the holeI I1 is the bar I23 and at the two sides of the hole III are the barsI25 and I28. The wedge I21 is utilized to shift the sheet I2 downwardlywith respect to the plate H6 until its lower edge is in proper positionon the bottom sheet l3 for welding. The wedge I28 is utilized to shiftthe bottom sheet l3 laterally with respect to the plate IIB to providethe proper projecting marginal edge I! prior to the welding operation.

In Fig. 8, I have shown a modified form. As

here shown, 2lfl,.2ll and 212 may also indicate sheets or plates ofsteel forming the side wall, for example, of a cylindrical tank. Forholding the sheets 2Hland 2l2 or 2H and H2 together, I

provide plates 2I6 with reinforcing flanges 2I6'.

The plates 2|6 with the reinforcing flanges 2l6 may be formed by usingchannel irons.

The plates 2 l6 are provided with apertures 2|! and MB adapted toreceive apertured holding lugs 2I9 and 220 .on the sheets 2H and 212. HIand 2 22 indicate wedges adapted to be driven through the apertures inthe holding lugs 2l9 and 220 to draw the sheets 2 and 2i2 against theplates 2l5 to bring these sheets into the same plane. If desired, theaperture holding lugs may be turned at an angle of 90 when fastened tothe sheet 2l2, as shown in Fig. 11, andin such case the holding lug 320is made somewhat longer so that its aperturewil] lie mostly above thetops of the flanges 216, as shown in Fig; 11. When so used, the wedge32| may lie on top of the flanges 2H5.

Although I have shown and described above the apertures as particularlyapplied for use in the welding of sheets of steel, it is obvious that itmay be employed in connection with the welding 01 members of any kind.The useof channel members as shown in Fig's. 8 to 11 is particularlyuseful in connection with the welding of cylindrical surfaces, such asshown in Figs. 10 and 11. The use of the invention permits theestablishment of a welding procedure which takes cognizance of the factthat shrinkage from welding is mostly across the joint, there being verylittle, it any, shrinkage in the direction parallel to the joint.

While I have shown and described certain embodiments of .my invention,it is to be .understood that it is capable of many modifications.Changes, therefore, in the construction and arrangement may be madewithout departing from bers to be welded together; wedges adapted to bedriven through the apertures in the holding lugs to draw the membersagainst the plate; a shoul der on the plate adjacent an aperture in it;and a ing lug and the shoulder toshift the member laterally with respectto the plate.

3. Welding apparatus, including: an angular plate apertured-to receiveapertured holding lugs on members to be welded together in angularrelationship; wedges adapted to be driven through the apertures in theholding lugs to draw the members against the plate; a shoulder on theplate adjacent an aperture in it; and a wedge adapted to be drivenbetween a holding lug and the shoulder to shift the member laterallywith respect to the plate.

4. Welding apparatus, including: apertured holding lugs adapted to beattached to members to be welded together; an angular plate apertured toreceive said apertured holding lugs when attached to members to bewelded together in angular relationship; wedges adapted to be driventhrough the apertures in the holding lugs to draw the members againstthe plate; a

shoulder on the plate adjacent an aperture .in it; and a wedge adaptedto be driven between a holding lug and the shoulder to shift the memberlaterally with respect to the plate.

5. Welding apparatus, including: a plate apertured to receive anapertured holding mg on a member to be welded to another member; a wedgeadapted to be driven through said aperture in saidholding lug to drawsaid member against said plate; a shoulder on said plate adjacent saidaperture; a wedge adapted to be driven between said holding"lug and saidshoulder to shift said member laterally with respect to said plate whensaid member is drawn against said plate; and means for attaching saidplate to said other member.
